Update to dhcpcd-10.0.1 with the following changes:

* privsep: keep resources open rather than open/close
* dhcp6: OPTION_NTP_SERVER is now preferred over OPTION_SNTP_SERVER
* Misc bug fixes mainly around privsep for many platforms.
* Fix for reading the some BSD routing table entries.
* Fix reading authtokens from config.

Big new release, mainly around better privsep process management
which allows us to detect when they exit unexpectedly.

* ipv6: disable kernel RA if interface is active
* hooks: set protocol to link for link layer events

branches: 1.1.1.1.2; 1.1.1.1.4; 1.1.1.1.8;
Import dhcpcd-7.0.0-beta. Changes from prior version include:

* source file locations reworked:
dhcpcd source is in src
dhcpcd hooks are in hooks
compat is in compat
* README split into README.md and BUILDING.md
* internal routing is now protocol agnostic
* avoid using __packed and use compile time asserts instead
* addresses some alignment issues
* disable some ARP code on kernels which support RFC5227
* BSD IPv6 kernel settings are now updated to reflect dhcpcd config
* custom logger has been removed, syslog handles everything
as such, the --logfile option has been removed as well.
If you need better/earlier logging, get a better syslogger!
* distinfo and signed distinfo files are now available alongside
release taraballs from this point onwards
* default DBDIR has changed from /var/db to /var/db/dhcpcd
* /etc/dhcpcd.duid moves to DBDIR/duid
* /etc/dhcpcd.secret moves to DBDIR/secret
* lease file names have dhcpcd removed from them as they are now
inside a directory of the same name
* fixed issues with reject routes not working on some platforms
* improved nl80211 support on Linux for working out the SSID
* no longer request NTP by default in dhcpcd.conf
* BPF filtering vastly improved so dhcpcd only wake up on
ARP or DHCP packets destined for it
* support for MUD URL (draft-ietf-opsawg-mud-05)
* if the kernel isn't doing DAD, don't insist on waiting for it
to actually do it
* fix a potential crash where the DHCP or ARP states could be
freed before the packet processing loop naturally breaks
* removed gateway and nogateway options
(these can be controlled by the nooption directive which
works for more than just gateways)
* removed ipv6ra_own and ipv6ra_own_default options
(these can be controled by the ipv6rs/noipv6rs directive)
* fix a crash receiving SIGUSR1

Import dhcpcd-7.0.0 with the following changes:
* dhcp: when unicasting on L3, unicast on L2 as well
* dhcp: when rebooting, don't set cidaddr
* dhcp6: don't listen on IPv6 addresses when not using DHCPv6
* dhcp: only set probe state when probing (fixes REBOOT reason)
* ipv6: disable kernel RA if interface is active
* hooks: set protocol to link for link layer events
